Inverter on (item 6) This green pushbutton is used to start the inverter. When it is pushed, the
green “load protected” LED flashes for three seconds, indicating that the start
command has been received. When the inverter has synchronized with the bypass
AC input (mains 2) source, the static switch transfers the load to the inverter output.
If the inverter cannot synchronize to the bypass AC input (mains 2) source, the load
must be forced to transfer using the hidden panel (see section 2.11, Forced
Transfers).
Inverter off (item 7) This gray pushbutton is used to stop the inverter. When it is pressed for 3
seconds, the inverter stops and the load is transferred to the bypass AC input (mains
2) source. If the uninterrupted transfer conditions are not met, this pushbutton has
no effect and the inverter can be stopped only from the hidden panel (see Section
2.12, Forced Transfers).
